| Popis: | This paper presents a method of calculating the recovery overvoltages in a HVDC circuit and the optimization of the damping circuit by selecting the lowest value of the damping circuit capacitance and the resistance which together satisfactorily limit the recovery voltage. Furthermore, a new method is developed for exact calculation of the losses in the damping circuit using a hybrid computer. The effect of the bridge operation (commutating and delay angles) and damping circuit parameters on the losses are analyzed using numerical examples. Finally, a method for designing the valve damping circuit is presented. |
